Blue MDPE or hosepipe?

I think bacteria need sunlight and air to breed.

Not the anaerobic varieties, they use different nutrients plus a whole raft of various fungi can develope

under such conditions - most being detrimental to people .consuming' them.

And even aerobic types only require oxygen and that can be obtained from more than just water.

I have moorings at the end of my garden. I installed a garden tap some way from the canal but have a 100m hose on a cart which spans the difference. We use a filter for drinking water, so feel that we're safe enough with that. We keep the hose out of sunlight and flush it through before filling from it (no idea how long one should flush for but do it until it 'feels right'). As for "food grade", I'm not bothered as I have no intention to eat it!

My garden tap was installed using the hard blue stuff. At mains pressure I feel that things are more likely to escape from it than enter. In your case, I'd put a tap/valve/stopper at the inlet end to prevent stuff getting into the run whilst not in use, then give it a good flush before using it. My memory is fading and mind less agile as I get older but I don't believe that's anything to do with what I might have picked-up in the water.

Be wary of freezing conditions, though. If it freezes-up, you may need to find other ways of getting it to the boat - and then have to check for leaks. I think bacteria need sunlight and air to breed. Lagging the exposed parts could be a good move.

 

Flushing a tap for testing purposes is two minutes, so zi reckon two mi uses after the water reaches the pipe outlet, if the ends are contaminated by canal water best to put it in a bucket of water containing bleach, about 4oz per 5 ltres!

10mm copper pipe adapted into the standpipe above flood levelwith a valve on the end by the Boat. Could be routed around bends with no connectors anywhere. Copper is hygeinic and durable and no chance of porosity. No hurry to fill the tank if one is there all the time anyway. 

 

Usually with standard hoses and taps there is some sort of time constraint. 

 

 

If it is a shared tap then let others do what they want to do but IF allowed I would definitely do it like that. The mooring I had was CRT owned with modifications not allowed but if one were installing the thing oneself it gives options to do it in a different way.
